Safari Would Not Connect
How can you stop searchmaster? Don't suggest downloading Malwarebytes! After trying it, my Safari (and Chrome) browsers would not connect to the internet. I uninstalled Malwarebytes, but that didn't work. After running diagnostics, one suggestion was to uncheck the web proxy HTTP from list of protocols. (System preferences, Network, wifi, advanced, proxies tab). That did not work.
After thinking about It I remembered seeing another proxy checked. Went back and unchecked Socks, then clicked OK. Thankfully, that fixed it and my browsers connected. I don't know if Malwarebytes caused this or it was because they quaranteed something (ADWARE, etc.) that caused this.
